This V-belt transmits drive from the engine or gearbox to the grain-tank auger on a combine harvester. It sits in the belt path between the drive pulley and the auger input pulley, converting rotational motion into the auger’s rotation for moving harvested grain into the tank. A worn or slipping belt reduces auger speed, leading to grain buildup or bridging at the tank inlet. The belt is constructed by Gates to match the original cross-section and length, which ensures correct tension and pulley contact without requiring shimming or adjustment of the idler. On installation, verify the belt is seated fully in both pulley grooves and that the tensioner is set to the specified deflection.
